From "Scale Expansion" to "Value Realization": The Global Battery Energy Storage System (BESS) Enters a New Phase of Development
In 2026, the global Battery Energy Storage System (BESS) industry stands at a critical historical juncture. After several years of hyper-growth, the sector is no longer simply pursuing "bigger and more"—it is undergoing a profound internal transformation: shifting from scale-driven to efficiency and value-driven, and from policy-driven to market-driven.

2026 is undoubtedly a "banner year" for the global energy storage market. The numbers speak for themselves: global new BESS installations in 2025 surpassed 100GW for the first time, nearly three times the 2023 figure, and 2026 is projected to exceed 130GW/350GWh. The market "heat map" has expanded from the traditional strongholds of China, the U.S., and Europe to emerging regions such as the Middle East, Australia, and Latin America.
- Europe: Surging Demand, Policy Acceleration: Europe added 36GWh of battery storage capacity in 2025, a 48% year-on-year increase. Extreme weather events leading to "summer power shortages" exposed structural weaknesses in its energy transition and have pushed policymakers to accelerate storage deployment. The EU requires 200GW of storage capacity by 2030, yet current capacity stands at only about 55GW—a vast gap indicating that the market is far from peaking.
- The Middle East: Mega-Projects as New Growth Engines: Middle Eastern countries, particularly Saudi Arabia and the UAE, are leveraging the "solar + storage" model as a core pillar of their "Vision 2030" strategies. Saudi Arabia's SPPC second-round BESS tender released a massive 12GWh of capacity, while Abu Dhabi's RTC project is planning an epic 5.2GW solar + 19GWh storage scale, aiming for 24/7 uninterrupted clean power supply.
- North America and Australia: Storage Begins to "Replace Natural Gas": In the U.S., the electricity demand from AI data centers has become a major driver for utility-scale storage deployments. In Australia, Victoria's battery power generation surpassed gas-fired generation for the first time in 2025, signaling that storage is transitioning from a "supporting" role to a "core" one.
In this global boom, Chinese energy storage companies have become the undisputed mainstay. In the first half of 2026 alone, Chinese companies have secured public orders exceeding 90GWh in the European market; in the Middle East's RTC projects, the storage equipment is almost entirely supplied by Chinese firms. From cells and system integration to EPC, China's energy storage supply chain is deeply participating in global competition with its cost, technology, and production capacity advantages.
China's Domestic Market Transformation: From "Mandatory Allocation" to "On-Demand Usage"
Compared with the boom in overseas markets, China's domestic energy storage market is undergoing a more profound reshaping. A landmark event was the issuance of the "Document No. 136" by China's National Development and Reform Commission (NDRC) in 2025, which ended the mandatory requirement for storage allocation for new wind and solar projects.
This seemingly "cooling" policy is actually a critical step in pushing storage from a "policy burden" toward "market value." Energy think tank Ember noted that the story of China's battery storage is no longer defined by how many gigawatts are added, but by how well that storage can support the new power system. Data confirms this shift: in the first four months of 2026, independent storage accounted for as much as 84.7% of newly installed capacity. These independent entities can directly participate in electricity market trading, generating revenue through peak-valley price spreads, ancillary services, and other mechanisms.
At the same time, the utilization rate of new energy storage has been improving year by year. According to the National Energy Administration, the equivalent utilization hours of new energy storage nationwide increased from 611 hours in 2023 to 1,195 hours in 2025—nearly doubling. This indicates that storage assets are no longer "ornaments" but are genuinely playing a regulatory role in the power grid.
AIDC Energy Storage: A "New Blue Ocean" in Technology and Business Models
2026 is widely regarded as the first year of large-scale deployment for AIDC (AI Data Center) energy storage. The explosive growth of AI computing power has made electricity supply a core bottleneck for computing infrastructure, and energy storage has been elevated from "energy support" to "compute necessity."
This new application scenario places entirely new demands on storage technology: high-rate, high-safety, and fast-response. In response, the lithium battery sector has seen targeted product competition, with companies like REPT Battero and Great Power launching 85Ah high-power cells that support 10C or even higher-rate short-duration discharge to meet the extreme backup power scenarios of data centers. Meanwhile, sodium-ion batteries, with their excellent rate capability and low-temperature performance, are carving out a differentiated market segment in AIDC storage, with players like Envision AESC and CATL already making strategic moves.
The market potential is enormous. Industry estimates project that by 2030, global AIDC energy storage lithium battery shipments will exceed 300GWh, representing roughly 20-fold growth compared to 2025.Challenges and Outlook: The Race Enters the "Second Half" Despite the bright prospects, the global energy storage industry faces real-world challenges.
- Profitability Pressures: In China, upstream raw materials like lithium carbonate are seeing price rebounds, while bidding prices for energy storage systems continue to decline. Combined with the difficulty of fully realizing multiple revenue streams from electricity markets, storage integrators' profit margins are being squeezed.
- Safety and Compliance: Globally, over 160 accidents at electrochemical energy storage power stations have been recorded. China's new regulations, effective July 2026, classify storage stations lacking critical grid-performance capabilities as major safety hazards. This tightening "red line" on safety and compliance is accelerating industry consolidation.
- Supply Chain Restructuring: Against a backdrop of geopolitical tensions, overseas markets are demanding greater localization of production and local service capabilities. The pure product-export model is no longer sustainable, testing companies' global operational capabilities.
The global energy storage market in 2026 stands at a threshold where "quantitative change" is about to give way to "qualitative leap." For Chinese companies, the "order race" of the first half is over; the "value race" of the second half—competing on product performance, project returns, and global service capabilities—has just begun.
